Abstract:
A multi-speed transmission has input and output shafts, gearsets (RS1, RS2, RS3, RS4), shafts (1, 2, 3, 4, 5, 6, 7, 8), and shifting elements (A, B, C, D, E). A carrier of gearset (RS4) and the input shaft couple as shaft (1). A carrier of gearset (RS3) and the output shaft couple as shaft (2). Sun gears of gearsets (RS1, RS4) couple as shaft (3). Ring gears of coupled gearsets (RS1, RS2) respectively form shafts (4, 8). Sun gears of gearsets (RS2, RS3) couple as shaft (5). A carrier of gearset (RS1) and a ring gear of gearset (RS3) couple as shaft (6). A carrier of gearset (RS2) and a ring gear of gearset (RS4) couple as shaft (7). Arranged within the power flow: elements (A, B) are respectively between shaft (3, 4) and a transmission housing; element (C) between shafts (1, 5); element (D) between either shafts (2, 8) or (6,8); element (E) between two of shafts (5, 7, 8).
